Mai and tyler work on the equation 2/5b+1=-11 together. mais soulution is b=-25 and tyler’s is b=-28. here is their work. do you agree with their solutions? explain or show your reasoning.

mai’s work : tyler’s work:
2/5b+1=-11 2/5+1=-11
2/5b=-10. 2b+1=-55
b=-10•5/2. 2b=-56
b=-25. b=-28

hellp me

No I don't agree with their solution; both their answers are wrong.

Correct answer is .

Step-by-step explanation:

Given:

Now given:

According to Mai and According to Tyler

Now we need to find which of them is correct.

So we will solve the given equation we get;

Subtracting both side by 1 we get;

Now Multiplying both side we get;

Hence both of them are incorrect, correct answer is .

answer: i guess 105 degrees?

step-by-step explanation:

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
